Manufacturing technology of bidirectional inlet Suspended vertical semi submersible sump pump

The manufacturing technology of a bidirectional inlet Suspended vertical semi submersible sump pump includes a pump casing with an impeller installed inside, which is connected to the shaft, and the pump casing is connected to the outlet pipe. One side of the pump casing is equipped with an inlet port one, and the other side is connected to the casing outside the shaft. The casing is equipped with an inlet port two, and the inlet port one is equipped with a filter screen. There are two filters installed on the inlet port two, and they are set on both sides of the casing. Through the above technical solution, the problem of poor sealing effect of the shaft seal of the vertical semi submersible sump pump in the existing technology has been solved.

[Technical Introduction]

As a key equipment in solid-liquid two-phase material pipeline transportation systems, submersible slurry pumps are widely used in industries such as mining, metallurgy, coal, water conservancy, power, transportation, papermaking, and environmental protection. However, in the existing technology, there is a problem of poor shaft seal sealing effect in the use of vertical semi submersible sump pumps, which can easily cause leakage and affect the normal use of vertical semi submersible sump pumps. Therefore, it is necessary to develop a vertical semi submersible sump pump that can solve the problem of poor shaft seal sealing effect in existing technology.

Technical implementation ideas

This technology proposes a bidirectional inlet Suspended vertical semi submersible sump pump, which solves the problem of poor shaft seal sealing effect in existing vertical semi submersible sump pumps. The technical solution of this technology is implemented as follows: a bidirectional inlet vertical semi submersible sump pump, comprising: a pump housing with an impeller inside, the impeller is connected to the shaft, the pump housing is connected to the outlet pipe, one side of the pump housing is provided with an inlet, and the other side is connected to the shell outside the shaft, and two inlet ports are provided on the shell. Furthermore, a filter screen is installed on top of the water inlet. Furthermore, there are two filter screens installed on the second inlet of the water inlet, which are arranged on both sides of the housing. Furthermore, the housing and the pump housing are connected by a flange. Furthermore, the pump casing comprises a ceramic volute shell with an outer metal volute shell, wherein the metal volute shell comprises two symmetrical metal half volutes, and a rear guard plate is provided on one side of the ceramic volute shell near the rotating shaft. Furthermore, the pump casing is a double-layer structure with a hollow center in the middle. Furthermore, the rotating shaft comprises an upper shaft and a lower shaft connected by a universal joint, and the lower shaft is connected to the impeller. Furthermore, a bearing is provided on the rotating shaft, which is arranged inside the bearing seat. Mechanical seal one is arranged above the bearing, and mechanical seal two is arranged below it. Both mechanical seal one and mechanical seal two are arranged on the bearing seat. The beneficial effects of this technology are: 1. There are two water inlet ports on both sides of the pump in this practical application, which can realize water inlet from both ends of the pump casing. Because both ends of the pump casing can be filled with water, the shaft seal at the connection between the shaft and the pump casing in the traditional vertical semi submersible sump pump can be omitted.
